Document Summary
Group dynamics expert marvin shaw argued that all groups have one thing is common: their members interact. Group: two or more people who interact and influence one another. Psychologist john turner states that groups perceive themselves as us in contrast to them . Different groups help us meet different human needs to affiliate, to achieve, and to gain a social identity. Mere presence means that the people are not competing but a passive audience. Co-actors: a group of people working simultaneously and individually on a non-competitive task. Experiments found that the presence of others improves the speed with which people do simple multiplication problems and cross out designated letters. Social-facilitation: before: people perform simple tasks better in the presence of others, now: the strengthening of dominant (prevalent liking) responses owing to the presence of others. Sometimes our performances hinders in the presence of others.
